Europe’s first proclamation of religious tolerance came out of Transylvania in 1557 – a product of the Diet led by Queen Isabella.
“In order that each might hold the faith which he wished, with the new rites as well as with the old, that this should be permitted him at his own free will.”“The faith which he wished” meant either Catholic or Protestant – there were only two choices. By that time, the vast majority of Transylvania had become Protestant -- Catholic priests had been driven out, church property confiscated or given over to the Protestants -- so it was the Catholics who had more reason to be glad of the protections of official toleration. In fact, the greater and growing religious conflict in Transylvania was between two Protestant factions, over the Lord’s Supper.
It’s hard for us today to imagine how fierce and vicious a quarrel over something like that could be. The Lutherans held that the body and blood of Christ are present in the bread and wine; the Calvinists held that these are only symbols, and each side saw no worth or dignity in the people who didn’t affirm what they affirmed.
Queen Isabella died in 1559, leaving her then-19-year-old son, John Sigismund, to rule Transylvania. King John was Catholic then, but he would later convert to Lutheran for two years, and then to Calvinist for five years, before finally becoming the Unitarian King.
